JCLLIB – To specify the location of proc library and include jcl statements library.

Syntax:

//MYLIB1 JCLLIB ORDER=(proc-lib-name,include-jcl-group-lib-name)

In proc

//INCL INCLUDE MEMBER=samplinc

Where samplinc is a member of include-jcl-group-lib-name

PROCLIB – To specify the location of cataloged procs

 //PROCLIB JCLLIB ORDER=proc-lib-name

Points to remember:

• An INCLUDE statement is used to identify the member of a PDS that contains set of JCL statements ( which has DD and ouput jcl statements) called as INCLUDE group.
• An INCLUDE statement can appear anywhere after the JOB statement with one exception. If there is a JCLLIB statement, then INCLUDE statement should follow the JCLLIB statement.
• INCLUDE group should not contain JCL statements like JOB statements, PROC and PEND statements,JCLLIB statements, JES2 and JES3 statements and commands, DD * and DD DATA statements.
